I have tried to see Adders on Hatfield for the last couple of years, mostly without any real success, so a cool morning with sunny spells seemed ideal. Ideal it was. We found two straight away which posed nicely and a third individual that let me get within just a couple of feet. Despite this and over 250 shots I managed just a handful of 'keepers' probably due to using a monopod instead of tripod, though I suspect the latter would have caused too much disturbance.
Thanks to Stephen Dunstan for bringing this to my attention.
